How should we improve a very successful design even further ? - Well, we at CARF-Models asked ourselves that question very often – especially when the topic is aerobatics. Our TOC-proven Extra 330S already got many input from Pilots like Jason Shulman, but when he told us about the advantages of the Extra 260, we started listening immediatly. And not only to him. Also Frazer Briggs is known as a big Extra 260 fan and flew his own designed 260 up to the podium at the Tucson Aerobatic Shootout several times.
But why is the 260 so perfect for our kind of IMAC-style flying ? Well, take a closer look at the full size airplane: Wing and stabs are aligned very axial - the secret of every neutral flying plane. They are reasonable streched in wingspan – almost like a modern F3A design. Missing the counterbalances, the elevators perform very well in sequence flying and let the plance track perfectly. Another affinity to pattern planes. And last, but not least, its fuselage side-area is big enough to perform a good knife-edge in every situation, while still keeping a really good aerodynamic shape. Even a 80cc single cylinder like the DA or 3W 85 provides more than enough power for every maneuver. And is so much affordable than a 100cc twin engine ! And of course, our full-composite Extra 260 2.6m is so strong that the higher vibration level of a single won’t hurt the airframe, even after 1000 flights.
So far, so good. Let’s take a closer look at our 260. You know it – when there aren’t exclusive details , realizing new thoughts to make a modelers life easier – than it’s something, but not a CARF.
Let's take a closer look at the wings first. Have your ever heard of the "TAVS"-technology, developed by CARF-Models? Well, it stands for "Total Area Vacuum Sandwich" - making the wings so strong and stiff, no wooden or foam-sandwich plane can compete with. A rib and spare structure inside the wing is already prepared for the aluminum spar tube and all the servos. Its made from high quality balsa and plywood, and - where necessary - it is coated with fiberglass or carbon. All hardware to install the aileron servos is included. You'll find accessories for your choice of JR or Futaba servos in the hardware bag.
The stab's inner structure is made from fiberglass-coated balsawood to keep it lightweight. You have to glue in some plywood-frames to mount the servos. Again, there are frames for JR or Futaba included.
The fuselage is stiffened with kevlar and carbon fibers where necessary. The engine dome forms one unit with the rest of the fuselage to keep the vibration and noise-level at a minimum. All popular 100cc twin-engines fit under the easy-to-remove cowling, but also the very popular and affordable 80cc single-cylinder engines fit very well. Featuring an all-composite-structure, you don't have to fear any weakness of the structure because of the stronger vibration even after 1000 flights.
If you use a 80cc single-cylinder, a tuned pipe is highly recommended and fits in the fuselage easily.
On all our modern kits, we modified the landing gear mounting. We didn't make experiments, we just made it solid and massive to keep you happy, even if one landing is less than perfect. And if really something happens, the landing gear legs are quite easy to replace. Three screws and that's it - not that bad, isn't it?
What is the most important thing, a good IMAC plane has to be: Right, neutral. So what's the secret about that: There is no secret. Simply care about an axial wing and stab position and about the same fuselage side area above and below the wing axis. That's it. It doesn't take long to recognize, that we did our homework with our Extra 260. You'll need only a very very small amount of coupling during knife edge. A special feature, also the full-scale Extra 260 offers, is the stab without any counterbalances. Well, we don't want to lie, and there are not only advantages. We highly recommend to use 2 highest power digital servos, like i.e. the JR 8711, for each elevator. And please take always a look of parts getting sloppy and if so, replace them.
The good things are: You'll getting an amazingly clear and strong response to your elevator controls. Use it for the crispiest snaps you ever saw or for the insanest freestyle maneuvers. It's you on the controls, we only care about the right material.
While still providing enough fuselage side-area for the craziest knife-edge maneuvers, the Extra 260's shape is quite aerodynamic. Even with a classic 150cc Engine on canisters, you have more than enough power to beat the wind. You'll probably laughing about that tiny little breeze, when your friends are already taking their Yaks apart.
Look at these large, aggressive ailerons ! The Extra 260 is doing amazingly fast rolls. You don't even need ridicously big throws for that, thanks to the well-proven airfoil and the clean surface of a full-composite airframe.
You want to have all the benefits of a Yak, while still prefering the look of an Extra ? - Well, then the decision is easy: The CARF-Models Extra 260 has everything you’ll need.
